A circle has center (5, -4) and radius 8. Which gives the equation of the circle? A) (x + 5)2 + (y - 4)2 = 8
B) (x - 5)2 + (y + 4)2 = 8
C) (x + 5)2 + (y - 4)2 = 64
D) (X - 5)2 + Hy + 4)2 = 64

A

Step-by-step explanation:

if not A then B but i'm pretty sure A

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
